この考案は、限外ろ過膜等の薄いろ過膜を用いたろ過装置の改良に関する。 The present invention relates to improvement of a filtration device using a thin filtration membrane such as an ultrafiltration membrane.
【0002】[0002]
従来、限外ろ過膜等の薄いろ過膜を用いたろ過装置はよく知られている。特公 平3−55173号発明はその一例であり、この発明では、両面にろ過膜を張設 したろ板を一定の間隔をあけて多数並列し、これらのろ板間にろ過すべき原液を 流してろ液を取り出すようにしている。 Conventionally, a filtration device using a thin filtration membrane such as an ultrafiltration membrane is well known. The invention of Japanese Patent Publication No. 3-55173 is one such example. In this invention, a large number of filter plates having filtration membranes on both sides are arranged in parallel at regular intervals, and the stock solution to be filtered is placed between these filter plates. It is made to flow and the filtrate is taken out.
【0003】[0003]
上述のような従来装置では、ろ過膜の目詰りを防止するには、ろ過膜面に沿っ て原液を流動させて目詰り物を洗い流すのが一般的であり、この方法では、ろ過 膜の目に入った夾雑物は除去することができず、ろ過膜が一定限度まで目詰りす ると、分解して洗浄するか、ろ過膜を交換しなければならない。 In the conventional device described above, in order to prevent the clogging of the filtration membrane, it is common to flush the clogging substances by flowing the stock solution along the surface of the filtration membrane. The contaminants entered cannot be removed and if the filtration membrane is clogged to a certain extent, it must be disassembled and washed, or the filtration membrane must be replaced.

この考案は、上述のような課題を解決し得るものであって、その要旨とすると ころは、その両面にろ過膜を張設したろ板と、その両面にろ過膜の保護シートを 張設した中間板とを案内杆上に交互に並列し、これらろ板と中間板とを互いに連 結して同時に開閉するようにするとともに、これらろ板と中間板には、これらを 閉板したとき、互いに連通してろ板と中間板との間に構成されるろ過室に連通す る原液の供給路と、濃縮原液の取出路とを設け、ろ過膜を張設したろ板には、そ のろ過膜の背面のろ過床に開口するろ液の取出路を設けたものである。 This invention can solve the above-mentioned problems, and its gist is to provide a filter plate having filter membranes stretched on both sides thereof and a filter membrane protective sheet stretched on both sides thereof. The intermediate plates and the intermediate plates are alternately juxtaposed on the guide rods so that the filter plates and the intermediate plates are connected to each other to open and close at the same time, and when these filter plates and the intermediate plates are closed, An undiluted solution supply path communicating with the filtration chamber formed between the filter plate and the intermediate plate and an outlet path for the concentrated undiluted solution are provided. The filtration passage on the back side of the membrane is provided with an outlet for the filtrate.
【0005】[0005]
この考案に係る装置は、上述のように構成してあり、各ろ板および中間板を閉 板することにより、これらの間に一側の面がろ過膜で他側の面が保護シートより なるろ過室を形成することができる。従って、このろ過室に供給された原液はろ 過膜によってろ過され、そのろ液はろ過床を経てろ板の取出路から機外に取り出 すことができ、一方、ろ液を分離された濃縮原液は、ろ板および中間板の取出路 から機外に取り出すことができる。 The device according to the present invention is configured as described above, and by closing each filter plate and the intermediate plate, one surface is a filtration membrane and the other surface is a protective sheet between them. A filtration chamber can be formed. Therefore, the undiluted solution supplied to this filtration chamber is filtered by the filtration membrane, and the filtrate can be taken out of the machine through the filter bed through the outlet of the filter plate, while the filtrate is separated and concentrated. The undiluted solution can be taken out of the machine from the outlets of the filter plate and the intermediate plate.
【0006】 そして、上述のようなろ過運転を継続してろ過膜が目詰りしたときには、原液 の供給路から洗浄液を送ることでろ過膜面を洗浄して再生することができる。こ のような洗浄をしても、目に詰まった夾雑物のように除去できないものに対して は、ろ過床側から洗浄液を送ることによって目に詰まった夾雑物を裏面から押し 抜いて除去することができる。すなわち、ろ過膜を表面からと裏面からと正洗お よび逆洗できるもので、完全に目詰りを解消することができるものである。そし て、上述逆洗時には、ろ過膜に逆洗液の高圧力がかかるのであるが、この考案で は、ろ過膜の前面に近接して保護シートが設けてあるので、ろ過膜が膨張等して 破損するおそれがないものである。Then, when the filtration membrane is clogged by continuing the filtration operation as described above, the cleaning membrane surface can be washed and regenerated by sending the washing liquid from the feed passage of the stock solution. For such contaminants that cannot be removed by such washing, the cleaning liquid is sent from the filtration bed side to push out the contaminants from the back side to remove them. be able to. That is, the filtration membrane can be washed from both the front and back sides, and can be completely backwashed to completely eliminate the clogging. Then, during the above-mentioned backwashing, the high pressure of the backwashing liquid is applied to the filtration membrane.In this invention, since the protective sheet is provided close to the front surface of the filtration membrane, the filtration membrane does not expand. It is not likely to be damaged.
【0007】 また、この発明に係る装置では、ろ板および中間板を開板することでろ過室が 開かれるので、ろ過膜および保護シートに高圧の洗浄液を直接噴射することがで き、従って、目に詰まった夾雑物を除去することも可能である。以下、図面に基 づいてこの考案を具体的に説明する。Further, in the device according to the present invention, since the filtration chamber is opened by opening the filter plate and the intermediate plate, it is possible to directly inject the high-pressure cleaning liquid onto the filtration membrane and the protective sheet, and therefore It is also possible to remove the foreign matters that are clogged in. The present invention will be specifically described below with reference to the drawings.

【0011】 この考案に係る装置は上述のように構成してあり、ろ板3および中間板4を閉 板すると、図2に示すように、これらの間にろ過室14が構成されると同時に原 液の供給路3b,4aおよび濃縮液の取出路3c,4bが連結されて原液の流動 路が形成される。従って、ろ過室14に送られた原液は、ろ過膜12によってろ 過され、そのろ液はろ過床3a、取出路3dを経てパイプ10によりろ過槽11 に貯留される。一方、ろ液を分離された濃縮液は、取出路3c,4bを経て原液 槽8に還流する。すなわち、原液を分離ろ液と濃縮液とに分離することができる 。The device according to the present invention is configured as described above, and when the filter plate 3 and the intermediate plate 4 are closed, as shown in FIG. 2, a filtration chamber 14 is formed between them at the same time. The stock solution supply paths 3b and 4a and the concentrated solution take-out paths 3c and 4b are connected to form a stock solution flow path. Therefore, the undiluted solution sent to the filtration chamber 14 is filtered by the filtration membrane 12, and the filtrate is stored in the filtration tank 11 by the pipe 10 through the filtration bed 3a and the extraction path 3d. On the other hand, the concentrated liquid from which the filtrate has been separated flows back to the stock solution tank 8 through the take-out paths 3c and 4b. That is, the stock solution can be separated into a separated filtrate and a concentrated solution.
【0012】 そして、上述のようなろ過運転をして、ろ過膜12が目詰りしたときには、供 給路3b,4aから洗浄液をろ過室14に送ることによって、ろ過膜12を洗う ことができる。ろ過膜12の目に詰まって上述のような洗浄では除去できない場 合には、ろ過床3a側から洗浄液を送ることによって、ろ過膜12を逆洗するこ とができ、目に詰まった夾雑物を押し出して完全に除去することができる。この ろ過膜12を逆洗するに当って、この考案では、ろ過膜12の前面に近接してメ タルメッシュよりなる保護シート13が設けてあるので、逆洗液の噴射によって ろ過膜12が膨張等して破損することもない。When the filtration membrane 12 is clogged in the filtration operation as described above, the filtration membrane 12 can be washed by sending the cleaning liquid to the filtration chamber 14 from the supply passages 3b and 4a. If the filter membrane 12 is clogged with the eyes and cannot be removed by the above-mentioned washing, the filter membrane 12 can be backwashed by sending the washing solution from the filtration bed 3a side, and the clogged contaminants can be obtained. Can be extruded and completely removed. In backwashing the filtration membrane 12, in this invention, since the protective sheet 13 made of metal mesh is provided close to the front surface of the filtration membrane 12, the filtration membrane 12 is expanded by the injection of the backwashing liquid. It will not be damaged by doing so.
【0013】 以上は、ろ板3および中間板4を閉板した状態でのろ過膜12の洗浄であるが 、この考案では、各ろ板3および各中間板4を開板することによって、ろ過室1 3が開放されるので、ろ過膜12および保護シート13を高圧の洗浄液で洗浄す ることも可能である。この場合、ろ過膜12に高圧の洗浄液を当ててもろ過膜1 2が支持材上にあるので破損等するおそれはない。The above is the cleaning of the filtration membrane 12 in the state where the filter plate 3 and the intermediate plate 4 are closed. In this invention, the filter chamber 3 is opened by opening the filter plate 3 and the intermediate plate 4. Since 13 is opened, the filtration membrane 12 and the protective sheet 13 can be washed with a high-pressure washing liquid. In this case, even if a high-pressure cleaning liquid is applied to the filtration membrane 12, since the filtration membrane 12 is on the support material, there is no risk of damage or the like.
